Checkout@v2 fails without git submodules

[mkuligow]

After adding submodules support, checkout action fails on single repository. Roll back to version 2.0.0 fix the problem

/usr/bin/git submodule foreach --recursive git config --local --name-only --get-regexp 'core\.sshCommand' && git config --local --unset-all 'core.sshCommand' || : Error: fatal: No url found for submodule path 'MY_SINGLE_REPO' in .gitmodules Error: The process '/usr/bin/git' failed with exit code 128

Seems to be due to the release of v2.3.5, even v2.3.4 works fine.

I ran into this issue as well. The failed command seems to match #385 and #590. I'm not sure if the steps or cause is the same.

In my case, I have a vendored repository (3rdparty/STX) which originally contained submodules (in 3rdparty/STX/.gitmodules). I vendored it as a subrepo, but Git still thinks 3rdparty/STX/third_party/abseil is a submodule, but with no corresponding entry in the top-level .gitmodules. Now git submodule foreach --recursive git config --local --name-only --get-regexp 'core\.sshCommand' tries and fails to operate on the subrepo's submodules:

fatal: No url found for submodule path '3rdparty/STX/third_party/abseil' in .gitmodules

This is technically a duplicate of #354
